CORN-HUSKING MACHINE.

Specification of Letters Patent.

Patented March 26, 1907.

Application filed September 21, 1906. Serial No. 335,588.

To all whom it may concern.-

Be it known that I, I/VILLIAM S. RUsE, a citizen of the United States,and a resident of Twin Bluffs, in the county of Richland and State ofIVisconsin, have invented a new and Improved Corn-Husking Machine, ofwhich the following is a full, clear, and exact description.

This invention relates to certain improvements in corn-husking machines,and, more in detail, involves an attachment for said machines wherebythe machine is prevented from clogging up and all danger of injury tothe operator is obviated.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, in which Figure 1 is aperspective view of a corn husking machine having my improved attachmentsecured thereto. F ig'. 2 is a plan View of said attachment. Fig. 3 is avertical section on the line 3 3 of Fig. 2. Fig. 4 is an inverted planview. Fig. 5 is a vertical section on the line 5 5 of Fig. 2. Fig. 6 isa detail showing the manner of holding the corn against thehusking-rollers. Fig. 7 is a detail showing the means of attaching thecanvas to one of the rollers, and Fig. 8 is a detail showing the meansemployed for oscillating the rollers carrying the canvas.

In order to fully illustrate my improvement and the working thereof, Ihave shown in Fig. 1 a pers ective View of a common form of corn-hus ingmachine having husking-rollers 6, snapping-rollers 7, and gearing 8 foroperating the machine.

My improved attachment comprises a rectangular frame made up of sidemembers 9 and cross members 10, supporting at one end my improvedshaking mechanism, while within and below the frame is supported myimproved mechanism for preventing clogging of the husking-rollers. Thislatter mechanism comprises a sheet of canvas 1 1, extending entirelyacross the husking-rollers 6 and of a length substantially equal to theside rollers. This canvas has its opposite ends attached to rollers 12,which latter are secured to the frame by eccentrically-located pins 13,carried in journal-boxes 14 on the lower side of the frame at itsopposite ends. For facilitating these rollers 12 and the canvas carriedthereby I provide each of the pins 13 with bevel gear-wheels 15, adaptedto mesh with gear-wheels 16, located on a shaft 17, journaled inextensions on the side 9 of the frame. The shaft 17 carries an armconnected by a pitman 19 to any suitable source of power, whereby thearm 18 may be oscillated, and the rollers 12, which carry the canvas,may thus be rotated back and forth through approximately three-fourthsof a revolution. For varying the amount of rotation of the rollers Ipreferably provide the arm 18 with a pluralityof holes, to which thepitman 19 may be attached, so that the relative rotation of the rollers12 as compared with the throw of the pitman 19 may be varied at will. Asthe rollers 12 are eccentrically mounted and are adapted to rotatesimultaneously, it will be noted that the canvas 11 will be moved notonly back and forth longitudinally, but will at the same time be raisedand lowered at an amount depending upon the eccentricity of the rollers12. This canvas, as previously stated, is mounted directly above themain husking-rollers, and in order to hold it against the corn at alltimes I secure a plurality of strips 20, extending longitudinally of thecanvas on its upper side and securely fastened to the canvas.

Each of these strips 20 is carried by two bolts 21, extending upwardlyto corresponding strips 22, mounted to oscillate in journalboxes 23 onthe upper side of the frame. These bolts 21 preferably extend throughthe strips 22 and are provided on their upper sides with adjustable nuts24, and intermediate of the strips 20 and 22 they are provided withcoil-springs 25, so that the distance between the two strips may bereduced by upward pressure upon the canvas; but the distance between thestrips cannot exceed a maximum determined by the location of the nuts24. As the rollers 12 rotate upon their eccentrically-located pins 13the canvas is raised from the husking-rollers, and as the strips 20 aresecured to the canvas they move in the arc of a circle, with the strips22 as centers, so that all the points of the canvas are simultaneouslyraised and lowered and no sagging of the canvas at the central ortion ispermitted.

On t e under side of the canvas and directly below each of the strips 20and at points adjacent the ends are located strips 26, carrying aplurality of springs 27, adapted to engage with the upper side of theears of corn and hold them in contact with the husking-rollers, asclearly indicated in Fig. 6.

As these springs are carried by the canvas they move back and forthacross the rollers and serve to prevent the husks from clogging up andinterfering with the operation of the machine.

The main frame of my attachment may be adjusted to varying distancesfrom the husking-rollers in any suitable manner, but preferably by meansof straps 28, secured to the frame at one end and suspended from rollerson a shaft 29, mountedon the main frame of the huskingmachine. Byrotating this shaft 29, by means of a handle 30 the straps may be woundupon the shaft and this end of the frame raised and lowered at will. Theother end of the frame is provided with screw-bolts 31, passing throughthe extensions of the frame and contacting with the main frame of thehusking-machine. The frame of the attachment may be raised or loweredeither by the contact of the lower ends of these bolts with the mainframe or by the contact of the upper ends of the bolts with hooks 32,carried by the main frame.

For facilitating the fitting of the corn to the husking-rollers Iprovide a shaker comprising a board 33, having one end thereof extendingbeneath the canvas, as shown in Fig. 5, and having the lower sidethereof provided with a plurality of bafiles or partitionplates 34,serving to guide each ear of corn endwise onto the rollers. This board33 may be reciprocated back and forth, so that the bafliles -34 tend tobring each and all of the ears of corn into a longitudinal positionrelative to the rollers. For mounting and reciprocating this board Iprovide a plurality of arms 35, having one end of each pivoted to thecross member 10 of the frame and having the other end ivotally connectedto the board. All of t ese arms are connected by a bar 36, to which maybe secured braces 37, extendin to the lower end of the board to sup ortt e latter.

ounted on one of the cross members 10 of the frame is a bell-crank lever38, having one end thereof secured to a reciprocating bar 39, whichlatter has its opposite end pivotally connected to an arm 40 on theshaft 17. The opposite end of the bell-crank lever 38 is pivoted toabracket 41 and also to the connecting-bar 36. The amount of throw may bevaried by varying the point of attachment of the reciprocating bar 39 tothe arm 40.

In the operation of my improved attachment the sheet of canvas is movedback and forth across the husking-rollers and is simultaneously raisedand lowered, whereby the springs 27, contacting with the ears of cornand the husks, prevent the rollers from be coming clogged up and alsoserve to agitate the material being operated upon and hold the ears infirm contact with the huskingrollers. The shaker 33 operatessimultaneously with the canvas, and as it serves to direct the ears andstalks into the machine in a longitudinal direction it also serves toprevent'the device from becoming clogged and its normal operationinterfered with.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In combination with the rolls of a cornhuskingmachine, a sheet of flexible fabric supported above said rolls, andmeans for mplving said fabric back and forth across said ro s.
